Parking device and parking system of automobile, and automobile

Abstract

A parking device of a vehicle is disclosed. The parking device comprises a parking gear, a position limiting member, a parking pawl, a push rod assembly, a swinging drive member and a position restoring member. The position limiting member is spaced from a circumferential side surface of the parking gear. The parking pawl is provided in the vehicle in a way that it is rotatable, and an engagement end of the parking pawl is located between the position limiting member and the parking gear, and is rotatable to a parking position where it is engaged with the parking gear. The push rod is provided with a pushing part that can abut between the parking pawl and the position limiting member. The push block is slidably provided on the push rod. An elastic member is connected between the pushing part and the push block. A swinging drive member can swing back and forth. A swinging end of the swinging drive member can be hinged to the push block to push or pull, via the push block, the pushing part to move by means of the elastic member. By pushing the pushing part the parking pawl can be driven to rotate so that the engagement end is rotated to the parking position. The position restoring member can provide a position restoring force to the parking pawl, so that the engagement end can be disengaged from the parking position after the pushing part is pulled.
